首予长光华芯"买入"评级，光通信产品市场规模稳步扩大
中邮证券 recent research report highlights Longlight Semiconductor's strong performance and market potential, earning the company a "buy" rating. The report points out that Longlight Semiconductor has achieved significant revenue and net profit growth in the first three quarters of the year, with non-operating expenses showing sustained improvement. With the market demand for semiconductors and high-performance chips soaring, the company has leveraged its IDM (Integrated Device Manufacturing) platform to deepen R&D efforts, successfully launching high-performance optical communication chips to meet the "domestic substitution" demand.
Longlight Semiconductor offers a comprehensive product portfolio, including EML (Electrical Multiplication), VCSEL (Vertical-Cavity Surface-Emitting Laser), and CW Laser, providing high-end chip solutions for the optical communication market. By the end of 2025, the company's 100G EML has entered volume production, with 200G EML ready for sample shipments. Additionally, 100G VCSEL, 100mW CW DFB, and 70mW CWDM4 DFB chips have also achieved mass production and are now available for shipment. The company is also actively exploring next-generation optical communication technologies such as silicon photonics (SiP) and thin-film lithium niobate (TFN), further solidifying its leadership in the technical competition.
